Blender fluid simulation fluid not colliding with effector's inside
@thibsert is correct: bottle had a gaping hole at the bottom, which I clumbsily sealed by adding a cylinder.
Also...
The Collision Effector surface thickness has to be at least 0.5 Thickness, which I have reported as a bug. And I have no idea why the default Sampling Substeps is '0', when I find that is often insufficient.  This also (unfortunately) implies that you'll have to have a duplicate, 0.5*2 larger scaled (hidden) effector, if you want to fluid to touch the sides and bottom of your bottle (workaround for the bug).
You also had &quot;Use Effector&quot; disabled, so it was ignored by the simulation.  I also increased the Domains Resolution Division, and decreased the particle size: often a pair of culprit contributors to poor results.
here is the resulting blend file:
